บทที่ 4 (Lesson 4) — Long Vowels II

Introduction

This lesson covers the remaining long vowels, including the important leading vowels that appear before the consonant. These are among the most common vowels in Thai and mastering them unlocks a huge portion of the language.

Leading Long Vowels

Remember: these vowels are written before the consonant but pronounced after it.

The เ-อ Combination

This vowel combines a leading เ with a trailing อ:

The Inherent Vowel

When a consonant stands alone without any vowel mark, it often has an inherent short "a" or "o" sound:

• ม alone can be read as "ma" or "mo"
• This is why you see words like มก (mok) without visible vowels

However, this is mainly for Pali/Sanskrit loanwords. Modern Thai usually marks vowels explicitly.

Common Words with Leading Vowels

• เป็น (bpen) — to be
• แม่ (mâae) — mother
• โต (dtoo) — big
• เธอ (thɤɤ) — you (she/her)
• เขา (khǎo) — he/she/they, mountain

Sound Guide for Leading Vowels

Key Points

1. Write left, read right: Leading vowels come before consonants in writing
2. No ะ = long: The absence of ะ indicates a long vowel
3. เ-อ is unique: A two-part vowel surrounding the consonant
4. Frequency matters: เ and แ appear in countless common words

Practice Reading

Try these common words:

• เด็ก (dèk) — child
• แก่ (gàae) — old
• โรง (roong) — building
• เบียร์ (biia) — beer
